A new CentOS 6 server install. Building a dedicated DNS server. Need to update all software. Tried "yum update" and I get

Determing fastest mirror
Fatal Python Error
Couldn't create autoTLSkey mapping

What did I miss to make this work?

did you by chance replace the version of python that is installed in Cent ?
yum REQUIRES that SPECIFIC version
the python that is in the Cent base( and updates) repo

No, I did reduce the etc/services list to tighten security and turned off some services. Does Python or Yum use any of those to find a mirror? What port does yum use? I may have it block in the firewall as well. Iptables rules are very tight right for both ingress and egress traffic. I'm not letting much out except udp:53, ntp:123 and tcp:53 to one address and tcp:22 for ssh.

Another pass at the issue. I stopped iptables and replace etc/services with the original services file and the problem continues...

Are you connected to the Internet?

rarebear.nm are you trying to update this cent6 install remotely ?

if so is it ssl or a VPN
and IS the cent 6 install the current ( and ONLY supported cent6 version) "CentOS 6.2" .

Yes there is an Internet connection. I can ping external addresses fine.

This system is still on the test bench and I only have a direct console connection to it right now. No remote connections have been setup or configured.

It is running CentOS 6.1.

Python/yum errors are almost always due to a blocked mirror.

rarebear.nm · 01-14-2012, 03:15 PM

Ok, so how do I identify blocked mirrors and how do I by pass this issue? Thanks.

I just tries yum --noplugins update - the update runs just fine. Any ideas where to go from here?
